Emerson KL2102X1-BA1 DeltaV Wireless I/O Card

The KL2102X1-BA1 wireless I/O card brings field signals into DeltaV systems without pulling long cable runs. Emerson designs this module for remote measurement points across process plants. It collects analog and discrete inputs, then transmits data over a wireless gateway link.

Channel Count and Signal Types

The card handles eight analog input channels and four discrete input channels in one housing. Analog inputs accept 4–20 mA current loop signals from transmitters and sensors. Discrete inputs read dry-contact and 24 VDC status signals from switches. Additionally, each channel includes overrange protection against wiring faults.

Radio Interface and Energy Storage

An integrated radio module communicates with DeltaV wireless gateways at 2.4 GHz. A supercapacitor stores energy for brief transmission bursts during low-power operation. The card draws under 20 mA in sleep mode, which extends field battery life. Consequently, remote nodes operate for months between battery replacements.

Physical Dimensions and Mounting Details

The housing measures 145 mm in length, 95 mm in width, and 50 mm in depth. It weighs roughly 0.6 kg, and it mounts on a flat panel or 35 mm DIN rail. Two compression glands accept field wiring with IP65 sealing protection. A rear connector links the radio antenna through a coaxial cable.

Installation and Commissioning Notes

Technicians mount the KL2102X1-BA1 near the measurement point and secure the antenna cable firmly. The card joins the wireless network automatically after power-up. Engineers then map each channel to DeltaV tags through the gateway configuration tool. Therefore, commissioning takes minutes rather than hours of cable work.

Why This Card Fits Remote Monitoring Projects

Plant teams choose the KL2102X1-BA1 for its mixed signal support and low power draw. Wireless transmission eliminates trenching and conduit costs at distant measurement points. The IP65 housing tolerates dust and washdown in outdoor installations. This card suits tank farms, water networks, and remote wellheads.
